Ah, tricky. It's the shared reverse of the Barber Dimes and later Seated Liberty Dimes. The surfaces to me look more like a Barber Dime, so that is my guess.
My first thought was an early Flying Eagle Cent. I used to collect "Indian Heads" and "Flying Eagles" and had all except the elusive 1856. EDIT: But it is not a Flying Eagle Cent. Methinks @Mr. Numismatist is correct. It has to be either a seated or Barber dime because the wreath's ends droop downward and actually touch rather than go straight across and leave a gap as on the Flying Eagle reverse. But to be ornery... ;-) ...I'll vote for a seated dime rather than Barber.
Yes, Barber or Seated dime was my first thought. I don't know how, if it's possible, to tell the difference based on the reverse, so I'll just go with Seated.
Waiting for @KBBPLL, @Treashunt and their Seated/Barber buddies to weigh in with the precise date range, if not the actual date and mint mark.
Tough one! Barber dime reverse was my first thought but it took a bit to confirm it. Would be much easier if you used the bottom half! Fun fact - the 1891 Barber pattern dime in the Smithsonian just straight up used the seated liberty reverse.
Not a seated liberty guy but they moved the motto to the obverse in 1860, which is the reverse Barber used. I don’t think there’s any way to ID the date or MM of a Barber from that snippet but it might be possible to say pre- or post-1900.
Barber Dime. The reverse wheat stalks of the Seated Dimes come much closer to the E in ONE than do those of the Barber Dimes.
You folks know your coins. Most of you identified it as a Barber Dime without much trouble. Kudos to KBBPLL for narrowing it down to the correct century, which, clearly, is why others were waiting for their input. As Maxwell Smart would say, "missed it by that much". The coin I photographed is ungraded, so there's nothing to confirm there. Here's the full coin image. I chose this particular crop for the detail in the wheat grains and the ear of corn. They stand out clearly on the coin, and the overall colour, contrast and texture are attractive. Thanks to everyone who took a guess. What will next week be?
